The more interesting question is: what do we do with the art of people who were revealed to be terrible? I first saw people wrestle with this idea for Michael Jackson and recently it has been a big issue related to Kanye West.
I don't really have an opinion on Wagner's music because he is dead. Michael Jackson similarly feels fine.
But it feels more and more terrible to stream Kanye, a contender for one of the best in producing and rapping, every time he opens his mouth because you know you're helping support his life style. But if you ripped his albums you can still enjoy the previous art.
But it's nice to know more about the riches finances and we should demand more. Papa John's fired their CEO for being racist, but he still holds significant stock, so I continue to avoid their pizza. Tesla could do the same and hopefully it still shouldn't matter without a complete sell off.
